5.0 CANBus Module Placement/System Wiring

Your CANBus system modules are all interconnected by means of Two Wires

- CANH (CAN High) and CANL (CAN Low) - plus the addition of a common shield wire. It is
Important to the operation of your CANBus system that the recommended module placement
and system wiring be followed very closely. Improperly placed/wired CANBus modules may
result in an inoperable system. It is important to carefully map out how you will route the
CANH and CANL signals from module to module so as not to compromise the signal
integrity because this information makes its way from one point to another on
your application.

Different Types of Modules
As received, the CANBus modules you have been supplied with

have been configured to be wired in a specific order based on your
application.
There are two types of modules your system could possibly use.

Full Termination : This is a CANBus module that has been

placed at the start or at the end of a BUS line

Stub Termination : This is a CANBus module that has been

placed in between the modules with full termination.

6.0 Identification Key

Each module in the CANBus system is assigned a unique Node Identifier that is registered in
the Master module ( most commonly the OCI-1 ) to perform a specific function for the system
as a whole. The CANBus system relies on an external resistive identification key which is
connected to the mating connectors of all Modules in the system (except the Master Module,
which always has
a “00” identifier ) This will allow you to plug a new replacement module into the
same location and have the system operational without initializing the new
module.

Systems where multiple modules of the same type may be used (e.g.,more than

one OCI-2 ) must use a unique Identification Key for each module. For
example, the first OCI-2 may use IDK-00 and the second OCI-2 may
use IDK-01, but they are not allowed to both use the same ID Key.

Consult the I-O sheet associated with your application for your specific Identification Key
assignments. Contact OEM Controls for the I-O Sheet that maps your application.

7.0 Human Machine Interface ( HMI )

The OCI-1 has an integrated multi segment , two line display with membrane keys that allow it to
be used as the main interface to system controls and adjustments. The Human Machine Interface
( referred to as the HMI ) will serve as your window into the application software to allow the
operator to monitor/adjust the following information;

- Active Function Being Used

- Part Number and Serial Number

- Restore the Factory Default Settings

- Output Calibrations ( Thresh,Max,Ramp.etc)

- I-O Status

8.0 CANBus LED Operation ( Based on CiA 303 Specification )

Each OEM Controls CAN Module has a BI-Color status LED, usually located between the
Deutsch connectors. This LED provides easy verification that the CANopen bus is
OK, and also allows easy system troubleshooting by illuminating Red, Green, or Amber ( Red and
Green on at the same time ).

In many cases, the BI-color LED will indicate two bits of information. For example, if the GREEN
led is on continuously, but the RED led is doing a “double flash”, this means that the can module
is in the operational state, but that a node guard error has occurred.

-When a module is first powered up, it enters the pre-operational state, with a green blink
indication. If there are no CANopen messages within 5 seconds, the module switches to
stopped, with red ON indication.

-One module, usually the OCI-1 “brain”, is also the NMT master (per CiA
Standard 301). As long as this module, and one additional module are detected
on the CANopen bus, the system automatically enters the operational state.

-At any time, if a module is powered on (for example, re-started) it will be
automatically set to operational by the NMT master.

-During normal operation, if no CANopen messages are received within 75
milliseconds, the module enters “failsafe operation” and turns off all of its local
outputs. After 1 second, the module enters the stopped state with red ON
indication.

-The OCI-1 provides additional bus information for each CAN module.

-The CiA Standard 301 specifies four states – the 3 above plus initializing which
occurs at power on reset. The OEM CAN modules automatically transition to
pre-operational after reset, per the CiA 301 spec.

Detailed Instructions ( For Layperson Users )

A serial (COM) port on your computer is used to communicate with the CANBus module using
standard RS-232 levels. Either the 9600 baud rate or the 115,200 baud rate speed may be used
(115,200 baud is recommended as it is 12 times faster). The additional serial port settings are:
8 data bits
no parity
1 stop bit
no flow control

Any terminal program may be used – the terminal program must support transfer of plain ASCII text
without any hardware or software flow control. All versions of Microsoft Windows come with a
standard terminal program called Hyper Terminal that may be used (see the following section for
instructions on setting up Hyper Terminal).

The serial (COM) port is connected to the product’s Optimizer plug with a special cable (available
from OEM Controls Inc.). One end has a standard “9-pin D” connector. The other end has a 4 or 5
pin Optimizer connector. Only 3 signals are used (TxD RxD and signal ground). Available cable
(part numbers) are:

EPWH/883 with 4-pin square connector, plugs directly into the product
EPWH/960 with 5-pin round connector, plugs into the system connector

The Terminal Downloader (TDL) feature has five commands –
H help – displays a list of the commands

L list – displays information about the product’s software and

hardware

P program – downloads a new software application to the product
R run – verifies the application and then runs it

Normally, you will only need to use the
sensitive (you may type them in upper or lower case).

Setting Up Hyper Terminal

The Microsoft Windows program “Hyper Terminal” can be found in the START menu – it is usually in
one of these locations:
Start – > Programs – > Accessories – > Communications (Win2000 WinXP)
Start – > Programs – > Accessories (Win95 Win98 WinME)

1. Start Hyper Terminal and then choose “Properties” from the FILE menu.

2. In the Properties window (shown below-left) choose Direct to Com 1 in the “Connect using:”
box (you may also use any other available COM port, such as Com 2).

3. Click on the “Configure” button. The COM1 Properties window (shown above-right) is
displayed. Set all five options –

Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

Then click on the Apply button, and then the OK button – this closes the COM1
Properties window. Finally, click on the OK button in the Properties window.

4. In the FILE menu, choose “Save As” This allows you to create a shortcut on your desktop.
Type in a descriptive name such as “115200 TDL” and click on the OK button.

From now on, you just click on the desktop shortcut icon to start using Hyper Terminal with the
Terminal Downloader.

A note to Microsoft Windows 2000 users – the standard version of Hyper Terminal shipped

with Win2000 is very slow when using a COM port. You may want to obtain and install an updated
version called “Hyper Terminal Private Edition” – it is available from the program manufacturer’s web
site http://www.hilgraeve.com

A note about File Types – the products application is contained in a text file (as Motorola S-

Records) with a .HEX extension. Applications sent from OEM Controls Inc. via email are always
compressed into a .ZIP file. The .ZIP file may contain one or more applications. You may use a
program such as WinZip to “unzip” the .HEX files. WinZip is available from the program
manufacturer’s web site http://www.winzip.com

5. Troubleshooting

a. If you are unable to communicate with the product.

i. Make sure the product is powered on.

ii. Check the cable connections on the computer and the product.
iii. Is the cable plugged into the correct COM port (there may be several)?
iv. Is the cable plugged into the Optimizer port (some products have other 4-pin

connectors used for other features)?

v. Check the Terminal program’s settings, especially the baud rate.
vi. Check the computer’s BIOS settings (make sure the COM port is enabled).

vii. Try re-starting (rebooting) the computer.

viii. Try re-starting the product (by turning its power OFF and ON)

b. If you cannot run the product’s application (the product is “stuck” in the TDL mode).

i. In normal operation, your OEM Controls, Inc. product always runs its

application software. However, several things could happen during
programming (downloading) that will prevent the application from running.

ii. The Terminal Downloader (TDL) performs several checks during

programming, and if problems are found (see the 3 bullets below) then the
TDL will not allow the application to run, and will stay in TDL mode.

c. Determining if the product is in TDL mode:

i. Many of the OEM Controls Inc. products have diagnostic LEDs (such as

“input” “cpu” and “output”) that blink sequentially during normal operation.
When the product is using the TDL feature, the LEDs blink slowly together
(they’re all ON or all OFF).

OM-17288

d. Programming (downloading) is interrupted before it is completed:

i. This could happen if there was a power failure (either the product lost power

or the computer lost power), or if the computer crashed, or if the cable
became disconnected. Because only part of the application was
programmed, it is not able to run.

ii. Action – repeat the P command to download the entire application.

e. An incorrect application was downloaded:

i. Each application is designed to operat e on a specific product (such as an

SB20X, an MRC10X, etc). Every product has a “device type” which the TDL
verifies with the software device type.

ii. Also, each product is manufactured with specific hardware options (for

example: 12V operation, tachometer input, diode-clamped outputs, etc) – this
is the “sub type”. The TDL also verifies that the product and software sub
type matches.

iii. Customers having more than one product could mistakenly download the

wrong file. Below is an example of what happens when the wrong application
was programmed.

iv. If incorrect software is downloaded into CPU A, the OCM-1 will not "boot" into

normal operation. It will power up in TDL_A mode with a yellow blinking CAN
led.

1. To FIX - download the correct software into CPU A.

v. If incorrect software is downloaded into CPU B, the OCM-1 will not "boot into

normal operation. It will power up with the CANopen communication
"stopped" and a "red-yellow" sequence blinking on the CAN led.

1. The LCD will display this message:
a. MISSING SOFTWARE ON CPU B

2. To FIX - download the correct software into CPU B.

f. "Incorrect Software" can be many things:

i. mixed up the HEX files for CPU A and B

ii. downloaded the wrong HEX file (say for a DMR30 application)

iii. incompatible revisions of OCO-2"A" and OCO-2"B" software

g. The application’s HEX file is damaged.

i. Software applic ations are provided by OEM Controls Inc. to the customer via

a computer file (which has a .HEX extension). The file may be sent by email,
in a .ZIP archive, or on a floppy disk or by some other means. The customer
may also copy or transport this file between computers. It is possible for the
HEX file to be damaged or corrupted.

ii. After downloading any application, the TDL always computes a checksum to

verify the program’s integrity. If the checksum is incorrect, the application will
not run, and the TDL will display a message.

iii. Action

1. try downloading this file again (in case there was just a computer

glitch) and if this fails, contact OEM Controls Inc. for a new copy of the
HEX file.
